Looking for $1000 speakers for my 2.0 -plz advise

I have my PC connected via USB to a Peachtree Decco.

The room is approx 12x12, I think the Decco should be enough to drive most speakers.

I watch movies occasionally but for the most part, it will be for music.

I was looking at the Sierra-1's for ~$900, don't think I can go wrong with a free home trial, but what are my other options?

I'm thinking towers would be overkill in a room this small, but then again, I don't want to add a sub either so I need something with decent bass.

I currently have Energy RC10's which I picked up for $300 from Vanns, they MSRP for $600 I think.

They sound really good, but I want something even better... not sure if $1000 will be enough to reach the next level though.

Any thoughts would be appreciated, thank you.
